To all whom it"ma'y concern": 1

Be it known that I, Louis Knssnnn, aci'tizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,-have invented certain new and useful Improvements in Devices for Preventprevent back firing from the carbureter or engine into the tank, or otherwise prevent the entrance of flame. The invention has among its objects the production of a device of the kind described for preventing back firing into a tank, that issimple, efficient, compact and satisfactory for the purpose, and which "may be inexpensively manufactured and installed in practically .any system at comparatively small expense,

and without much difiiculty. Other objects and advantages of the device herein described will be obvious to those skilled in the art to which the same pertains.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Figure 1 is a sectional view through my improved device, a portion of a receptacle and the discharge pipe therefrom;

Fig. 2 is a sectional view taken substantially on line 22 of Fig. 1;

Fig. 3 is a sectional View taken substantially on line 33 of Fig. 1, and

Fig. 4 is a perspective View of a perforated plate 13 and reinforcement and support therefor.

Referring to the drawings, 1 represents the tank or receptacle, and 2 a part secured thereto in any suitable manner, the same being tubular or provided with a chamber 3 therethrough. Carried by part 2 is a cooperating part 5, chambered as at 6, and formed with an outlet7, the part being suitably connected with the feed pipe 8, ,extending from thetank to where desired, as for example, to the carbureter of an internal combustion engine. The parts '2 and 5 are preferably, although not necessarily,

made separable, as shown, and together constitute a tubular part having an inlet and outlet. Preferably arranged at the inlet 4, and extending transversely across the part,

is a wire screen or gauze 9 of small. mesh,

so that flame will not pass therethrough. The screen 9 may be arranged or secured in place 1n any desired manner.

Also extending across the tubular part in the ,path of fluid passing from the tank to the discharge pipe 8, is a perforated protecting member or plate 13, or the equivalent, whi'ch is of some strength so as not to readily fracture, and which is carried by the part 10, formed with openings or notched as at 11, or in an equivalent manner, as most clearly shown in Figs. 3 and 4-. Part 10 is also provided with legs or lugs 12,

which abutagainst the shoulder 16 on part The perforated plate 13 may be secured to part 10 in any desired manner, as for example by forming a lug 141 on part 13, and then upsetting the end, 15 being a washer, which may be inserted if desired. I have shown the perforated plate 13 of a size to extend between the parts 2' and 5, as

most clearly shown in Fig. 1, so that the same is supported at the edges.

In the normal operation of the system the gasolene or other fluid freely flows from the tank through the gauze or screen 9, through the openings 11, and perforated plate 13,

- into the discharge or feed pipe 8, to where desired. In case of any back firing or entrance of flame through the pipe8 toward the tank, the force or shock of the back firing will be taken up by the plate 13, the flame, however, being prevented from entering the tank by the gauze 9. While the gauze in itself would prevent the flame reaching the interior of the tank, the force of the back firing might be apt to fracture or displace the same. The plate 13, however, receives the impact or shock, the same being reinforced by means of the part 10, which is solidly maintained in place by the lugs 12, abutting against the shoulder 16. The plate also prevents any fracture of the gauze from the exterior of the device when the discharge pipe is detached for cleaning or other purposes. The device is particularly adapted for automobile use, underground tanks, or the like, and eliminates any chance of back fire, causing an explosion in the gasolene tank.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construc tion, arrangement and combination of parts herein shown and described, and uses mentioned.

What I claim as new and desire to secure bv Letters Patent is 1. A device of the kind described comprising a chambered tubular part having a screened inlet and an outlet, in combination with a transverse partition arranged in said chamber and spaced from the screened inlet, said partition having a central closed body part and provided with a plurality of relatively small screened openings arranged about its periphery.

2. A device of the kind described comprising a chambered tubular part having a screened inlet and an outlet, in combination with a transverse partition arranged in said chamber and spaced from the screened inlet provided with a plurality of smaller screened openings arranged around its periphery, and bracing means for the transverse partition supporting the same in an outward dlrection.

3. A devlce of the k1nd described comprising a chambered tubular part having a screened inlet and an outlet in combination with a removable transverse partition ar ranged to be placed in the chamber, provided with bracing legs extending outward and positioned against the supporting wall of the chamber, said partition being formed with a plurality of openings arranged about its periphery, and a screen covering said opemngs. a

4.111 a deviceo'fl the kind described, a partition memlber provided with outwardly extending brace legs, and formed with openings aboutits periphery in combination with a screen arranged on the slde opposlte to the legs covering said openings, said screen be- In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
